Earthquakes can be far more than just geological phenomena—they can greatly alter the way we live. In this video, "The Great Southern California ShakeOut: An Earthquake Scenario Based On Science," USGS scientists and their partners talk about the ways science is used to help build safer communities in Southern California.

USGS scientist Ken Hudnut fills us in on how science created the theoretical magnitude 7.8 earthquake behind the Great Southern California ShakeOut—the largest earthquake preparedness drill in U.S. history, coming Nov. 13—and what such an earthquake would do to downtown Los Angeles.

What if you knew that a magnitude 7.8 earthquake would happen in less than three weeks? In this video interview, USGS earthquake scientist Dr. Lucy Jones explains that millions of Southern Californians will be preparing as if they do know, thanks to the Great Southern California ShakeOut.

Long-standing farming practices in California's Sacramento-San Joaquin River Delta expose fragile peat soils to wind, rain and cultivation, emit carbon dioxide (CO2) and cause land subsidence. To capture or contain the carbon, farmers would "grow" wetlands. In doing so, they would begin to rebuild the Delta's unique peat soils, take CO2 out of the atmosphere, ease pressure on the Delta's aging levees, and infuse the region with new economic potential. We learn more from USGS bio-geochemist Robin Miller about how this could help California, the nation, and the world. (8:34) | Transcript/Links | Download directly (7.92 MB) (right-click to save) |
